The red ones, of course, are the green ones turned late in the season. I have never been able to tell the difference in taste of the different varieties in red. The red chiles have a sweeter taste. They are also a little more difficult to peel. My favorite of all is when the chile is transitioning to red and is half green and half red. This is called "pinto". There is about one or two weeks at the end of the season when the "pintos" are out and they are to die for. For some reason, they seem hotter to me also. This may not make sense to the techie growers, but I my experience is they are sweeter and hotter. We use the red chile pods to make red enchilada sauce or dry them out for enchilada powder. Red enchilada sauce is a great marinade too.
